Definity™Vinyl Technology
The heart of the Sheffield platform is Definity vinyl. This advanced vinyl compound is rugged, durable and virtually maintenance-free. The material’s low thermal conductivity makes it the perfect choice for window manufacturing.
EliteWeld ™Fusion Welding
Every corner of the Sheffield Window features EliteWeld fusion welding, a technologically-advanced method of construction that delivers superior strength. The EliteWeld method produces fullcontact welding points and does not require below-the-face flash clean up.
Intercept Spacer System
The Intercept Spacer System features a unique, one-piece U-channel design that creates an effective thermal barrier to help reduce conducted heat loss through the window. Its sealed, one-piece design makes Intercept pacers stronger and better at retaining insulating gas than many conventional designs. Intercept spacers are so energy-efficient that they keep the edges of the window glass warmer, so your home feels more comfortable in the winter.
